Comment Generational turnover effect (Score 2) 70
I went to school 20 years ago and everything was (then still-alive) solaris/bsd or (then new) Linux. University web infrastructure, engineering school computer lab thin clients, etc.
When I started work, it was a little different, but the same effect. Most of the legacy systems were from the early 90s and made for solaris or hpux. And by the time it was time to port to a more modern os, us new kids naturally gravitated to the path of least resistance and least licensing costs. That was either pure oss linux or (eventually) red hat, which by virtue of being intended a mass market product competing or complementing purley oss solutions, was loads cheaper than something (by then) niche like a vendor-supplied unix system.
Windows got skipped over for everything except desk machines.
Now it's 20 years later and us greenhorns are turning into greybeards who've never in our careers seriously considered doing anything serious on windows.
